Usually, the HLR (via MSC) determines whether a subscriber is allowed access to a network, the BSC should have no say in this. The IMSI regex in osmo-nitb was a highly non-standard way to scratch a very specific itch, in the same way that osmo-nitb was maybe simpler to use, but hardly possible to integrate with a standard core network. So, no, there is no access management in osmo-bsc. In contrast, you need to add each subscriber to the HLR database (e.g. osmo-hlr) so that a subscriber is allowed to attach. ~N
